For the 6th time, the government has extended the deadline for individuals to link their Permanent Account Number (PAN) to Aadhaar. Now, the deadline for linking PAN with biometric ID Aadhaar is September 30. In last June, govt said that PAN has to be linked with the biometric ID by March 31. Quoting of Aadhaar will be mandatory while filing income tax returns (ITRs) with effect from April 1, 2019.
